GEORGE B. ROVVLETT, OF PHILADELPHIA, PENNSYLVANIA.

'SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 368,010, dated August 9, 1887.

Serial No. 236,6l0. (No model.)

To all whom, it may concern:

Be it known that I, GEoRe-n B. RO'WLETT, a citizen of the United States, residing in the city and countyof Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Sash-Tighteners, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a device operated by the movement of the sash-frame for tightening the sash and preventing rattling thereof.

Figures 1 and 2 represent side elevations of a sash-tightener embodying my invention. Fig. 3 represents a horizontal section thereof.

Similar letters of reference indicate corresponding parts in the several figures.

, Referring to the drawings, A represents a casing or box which is adapted to be secured to the side stile of a window-frame and having pivoted to it a plate, B, whose edge a toward the window f sash is curved or camshaped, whereby when the plate is rotated said edge jams against the sasli-frame, thus ti gb tening the latter against the window-frame.-

Secured to the plate, near the edge thereof, is a pin, O,which extends horizontally within the casing, and is located in the path of an arm, D, the latter being secured to the side rail of a window-sash above the casing A.

E represents a spring, which in the present case is coiled around the axial pin of the plate B and has one end connected or resting against the casing and the other end bearing upwardly against the pin O,whcreby the plate may be restored to its normal position, as in Fig. 1.

The operation is as follows: The arm D is so disposed that when the sash has nearly reached its lowest position it abuts against the pin 0, whereby the plate B rotates downwardly,and

thus against the sash-frame, and when the sash is fully lowered the plate is jammed or wedged against said frame, whereby the sashframe is tightened against the window-frame, so that the joint between the contiguous parts is closed and the sash is prevented from rattling. When the sash is raised, theplate is relieved of the downward pressure of the arm D and the sash released of the tightening action of said plate, the latter then rising or returning to its first position onto the spring E.

WVhile the casing forms the bearings for the axial pin of the plate B, it is evident that in lieu of said casing I may employ cars which have said pin secured to them and are provided with openings for the fastening-screws.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Asash-tightener consisting of a cam-faced pivoted plate attachable to the frame of the window and having a pin projecting therefrom, and an arm attachable to the sash, the pin of the plate being in the path of the said arm, whereby the said plate is rotated so that its canrface is wedged against said sash, substantially as described.

2. A sash-tightener consisting of a pivoted plate having a cam face and a pin and attachable to a window-frame, as described, an arm attachable to a sash,and a restoring-spring for said plate, the path of travel of said arm be ing in line with said pin at all times, so that said arm actuates said pin and rotates the plate, thereby wedging its cam-face against said sash, substantially as described.
